The structure increases the pressure of the airflow flowing out of the air outlet by reducing the air outlet of the first through hole 21, so as to prevent the material from falling through the hole.
In one embodiment, the other end of the feeding sliding plate 2 is provided with a second through hole 23, and the second through hole 23 is located at one end of the feeding sliding plate 2 close to the air supply hole 12 and is communicated with the inner cavity 11, i.e. the lowest position of the feeding sliding plate 2. The wind from the wind supply hole 12 forms a protective wind layer at the joint between the garbage and the fire grate segment through the second through hole 23, so that the garbage is prevented from sliding into the joint between the fire grate segment, and the sealing effect is not affected. The second through hole 23 is a strip-shaped hole, extends from one side of the feeding sliding plate 2 to the other side, and almost penetrates through the material self-sliding surface of the whole feeding sliding plate 2. In this way, a protective air layer can be formed at the whole joint to prevent garbage from sliding into the joint between the grate segments to the maximum. The moisture in the garbage may flow into the housing 1 through the second through-hole 23 and then enter the drainage system through the drainage hole 14 to be discharged.
In one embodiment, the second through-hole 23 becomes smaller from its inlet to its outlet.
